lrzip -vvi shows incorrect offset for stream 1

[pete4abw]

Examining the output of max verbose lrzip -vvi revealed that the offset shown for stream 1 is incorrect. It uses the same offset as stream 0. This occurs for all chunks. I believe this oversight has been around since

a023420 2011-03-13  Make get_filefinfo read over whole file to get uncompressed size for when it's not known due to being a stdout chunked file. Don't display microseconds in information as it will be removed.

I don't maintain a fork of lrzip anymore, but this patch will help. It is implemented in lrzip-next.
